Answer:
Explanation:
For spring
where n is frequency of oscillation and k is force constant and m is mass
Putting the values
k = .4032 N/m
F= k x
where F is force , k is force constant and x is extension
Putting the given values
1 = .4032 x
x = 2.48 m
Explanation:
The energy of the system before the collision must equal the energy after the collision.
After the collision the bullet and the block have a total mass of 18.41 kg and they move at a speed of 8.8 m/s. The kinetic energy after the collision is
Before the collision only the bullet has kinetic energy.
So we can now determine the speed of the bullet using
